Hi iBookG4G
I can't answer about the checksum business. I got the same thing on a powerbook G4 when using Disk Utility. The solution I found was to burn with Toast without mounting. After burning I copied the crack version to the same folder and added a 1 at the end of the file name. It all runs fine. Thanks queche!

I started splinter cell but by sensors on my laptop keyboard is broken so i have to use a keyboard attached to my computer(MAC). But i cant walk around IN SPLINTER CELL.. Is it because i got an attached keyboard? Or is it something else?

If u cant get the splinter vell to work. you have to press....I dont know what it is in english. but in norwegian it is "hopp over" butten when you are going to start the dmg. Instead of waiting till its done. When you open it you have to put the crack in the splinter cell mapp.(you have to make that mapp) and you have to putt the rest of the files in with it too. And to putt the crack inside you have to change the name of the splinter cell(non crack). after that you can put the crack inside the mapp with the rest of the things. And i have a MAC OS X INTEL. Leopard. versjon: 10.5.6 Sayonara!.
